slipfreak84 im not really on a time frame....i have a 91 chevy caprice....i have a 305 in it now, wanting to put the 350 in it.....we tested it, runs exceptionally well, oil pressure is at 70lb at idle, no leaks.....has a edelbrock performer intake, my caprice is tbi, getting a throttle body adapter plate, not sure if i should use the stock tbi (might restrict the fuel for the 350)....i dont want headers but i have duals already on it....getting a posi rearend....i am using this as a daily driver.....not worried about the gas price, just want it to be worth my while and i want the 350 to make people jealous or in a way just impressed that it runs really well

j.d.brown.042964 Slipfreak, what exactly are you wanting to do? Proper design for relative purpose intended is what will result in getting what you want, so far as what the end result will be. What kind of vehicle are you going to put it into? How much does it weigh? WHAT WILL IT BE USED FOR? Do you want to spend $9/gal for racing fuel, or do you want it to be able to run on 93 octane premium unleaded? Or 87 octane regular? Will it spend all of it's time on a circle track? On a dragstrip? Delivering pizzas?... DO you want this vehicle to have 160mph top end, or just an 11sec 1/4 mile, or something you can actually drive on the streets (comfortably) 6 days out of 7? Throw us a friggin' bone here! I suggest that for starters you spend an entire evening or two, or more, reading thru the knowledge base and getting some ideas on exactly what this engine(s)/vehicle(s) intended usage will be, and then you'll have a good starting point from which to begin the PLANNING phase. You do only want to pay for it ONCE don't you? If you just start throwing parts and components together that are not well-matched to each other AND to the "suitability of purpose", you'll end up with a high priced hunk of junk that will be slower that what you could've bought off a car lot, and unreliable/unsafe as well, in addition to being uncomfortable to drive and needing to be redone correctly from the start. Start out by doing some research, and thinking about what you want this vehicle to be PRIMARILY used for. Then decide on a budget and a timeframe. Then MORE RESEARCH... You'll be happier in the end.-Jim

roller rockers

I built my 350 SBC T bucket motor. with roller tip rockers, screw in studs, bronze valve guides. Hot hyd cam, and lifters (I forget the numbers) I am running a TH350 so the cam can't be too wild, new valve springs. dual 4 barrel carbs. bottom end bluprinted. It all has to work together. probably too much carb but 2 4's and an old school crab top mallory dual point distributor look cool.

Agree, that's the key
DEPENDING ON WHICH ROLLER ROCKERS YOU USE.

You might need new pushrods due to length/geometry.
You might cause the valve keepers to hit the seals if you go to more ratio, or even spring bind.

Either way, you might gain 5 hp.
You should consider other modifications to be more important.
